Brendan Battersby
Network Engineer
Designing, building, and securing modern enterprise network infrastructure
9 years of experience in routing, security, cloud
About Me
I take projects from whiteboard to production. My recent work has included leading a network architecture redesign from static to dynamic eBGP/OSPF routing, building redundant hybrid cloud connectivity to Azure with Velocloud NVAs, and implementing zero-trust policies with Zscaler across 2500+ endpoints. I care about clean design, clear documentation, and no shortcuts. When I'm not designing networks, you'll find me lifting, hiking, or playing DnD.
